5. Remember: The magnitude of a vector V is the ‘length’ of the vector. Above you find how to calculate the magnitude in 2 dimensions (use the Pythagorean relation | V | = x 2 + y 2 . In 3 dimensions you can simply use | V | = x 2 + y 2 + z 2 (see text book.) If you are given a vector as V = x* i + y* j + z* k , then x,y,z are the x, y, and z components of the vector. The magnitude |
